Look at a globe. A globe shows us what the Earth looks like. It is a model of Earth. Earth is shaped like a ball or a sphere. What colors do you see on the globe? You see a lot of blue. That's the water in Earth's oceans. Earth has more water than land. There are five named oceans. There are seven large masses of land called continents.
Around the middle of the globe, you will see a line called the equator. The equator divides the Earth in half. The equator is like a belt that goes around Earth's middle. The top half of the Earth is called the Northern Hemisphere. (The word "hemisphere" means half a sphere.) The bottom half of the Earth is called the Southern Hemisphere.
Lines that run across the globe from side to side are called lines of latitude. Lines that run from top to bottom are called lines of longitude. These lines are like a ladder. Lines of longitude are like the sides of a ladder. Lines of latitude are like the steps on a ladder.
